What is CRT?

Explanation
CRT stands for Cathode Ray Tube. A cathode ray tube is a vacuum tube that contains an electron gun and a fluorescent screen. When an electric current is applied to the electron gun, it emits a beam of electrons that strikes the fluorescent screen, producing an image. CRTs were commonly used in older television sets and computer monitors. They have been largely replaced by flat-panel displays such as LCD and LED screens, which are thinner and more energy-efficient.

What is Modem?

Explanation
A modem is a device that modulates and demodulates signals, allowing computers or other devices to transmit and receive data over a network. It converts digital data from a computer into analog signals that can be transmitted over telephone lines or other communication channels. On the receiving end, it demodulates the analog signals back into digital data that can be understood by the computer. Therefore, a modem acts as a translator between the digital signals used by computers and the analog signals used by communication channels.
